Title: Method for assembling magnetic disk medium
Inventor: YAMAMOTO KIMIZO
IPC: G11B23/00
Filed: 1988-09-19
Abstract: PURPOSE:To prevent a chip due to the contact at the time of assembling from generating by laying a resin type thin buffer between a magnetic disk medium and a spacer ring and the hub of a spindle. CONSTITUTION:A resin type thin buffer 11 is laid between the outer circumference of a hub 3 of a spindle and a magnetic disk medium 5 and a spacer ring 6. Thus, while the thin buffer 11 composed of a resin type low friction material is laid, the medium 5 and the ring 6 are alternately inserted and piled to the outer circumference of the hub 3. Thus, when the ring 6 is inserted into the outer circumference of the hub 3, the medium 5 and the ring 6 are not directly contacted with the hub 3. For this reason, two metals are rubbed, contacted and thus, the chip is not generated.

Title: Production of anisotropic floppy disk
Inventor: SUZUKI HIDEO
IPC: G11B5/845
Filed: 1983-12-12
Abstract: PURPOSE:To obtain an anisotropic floppy disk which is free from variance of the output level, etc. due to the disk revolving angle, by orienting the magnetic recording liquid applied to a disk substrate in the revolving direction of the disk substrate. CONSTITUTION:A nonmagnetic sheet 11 is blanked into a disk of a prescribed size. A disk substrate 12 is attached to a rotary head 15, and a magnetic recording liquid A is sprayed to the fringe part of a center hole 13 of the substrate 12 through a nozzle 16. As the substrate 12 is revolved at a set speed, the liquid A is widely diffused toward the outer fringe part of the substrate 12 and then applied to the entire area on a single side of the substrate 12. A rotary head 18 containing the substrate 12 is revolved at a prescribed speed, and a magnetic field acts on the liquid A by means of a magnetic head 19. The head 19 has two head bars 21 and 22 having hook-shaped tips on a substrate 20 with a gap (d) secured between them together with a magnet 23 held between both head bars. The layer thickness of the liquid A is gradually unified as the liquid A passes through the head 19. Thus the smooth orienting process is ensured.

Title: On-vehicle acoustic reproducing device
Inventor: TERAI KENICHI
IPC: H04R5/02
Filed: 1986-10-02
Abstract: PURPOSE:To obtain distinct sound image localization between two speakers in the front seat by correcting time lag corresponding to difference of distance of two speakers installed in front of the front seat from a specified position by a delay means. CONSTITUTION:Even if the balance of input signal level of speakers 9, 10 is adjusted so as to be just the center of front speakers 9 and 10 from the front monoral sound image localization position 18, phase is deviated since the distances from two front speakers are different, and the quality of sound image localization is poor. Accordingly, input signals from the front speaker 10 is delayed by a delay element 3, and the distance between the two front speakers and a listener is made coincident. Thereby, the phase of sound from two speakers is aligned, and the sound image is positioned distinctly, at the speaker position 19.

IPC: A24D3/08
Filed: 1985-10-23
Abstract: PURPOSE:To effectively remove a carcinogen, by using lignin, which is obtained by a method wherein a wood powder is extracted with a solvent and the extract is filtered to form a residue which is, in turn, subjected to acid treatment and subsequently washed with water, as a carcinogen adsorbent. CONSTITUTION:For example, 300ml of an alcohol/benzene solvent mixture (1:1) is added to 30g of fir chips and a reflux cooler is used to perform extraction for 8hr. The extract is filtered to form a residue which is, in turn, washed with alcohol and, after drying, 300ml of 42% hydrochloric acid to the residue and the resulting mixture is stirred for 3hr on an ice bath. Subsequently, the treated mixture is allowed to stand at 0 deg.C for 17hr and 90g of ice is added thereto to perform stirring for 3hr and acetone is added to the residue before filtering. Thereafter, the residue is washed with benzene in the same way and finally washed with methanol and dried in air to obtain 10g of lignin. When this lignin is added to an aqueous solution of a carcinogen, said carcinogen is effectively adsorbed.

Title: Brake booster device
Inventor: OKUNO TSUYOSHI
IPC: B60T13/57
Filed: 1997-08-15
Abstract: PROBLEM TO BE SOLVED: To enhance the responsiveness of a brake booster device while making the pedaling power needed to step on a brake pedal from a servo balanced state smaller than in devices of the prior art. SOLUTION: A rubber damper 33 is provided between the valve plunger 17 and the plate plunger 34 of a brake booster device. Brake reaction is transmitted to the valve plunger 17 via an output shaft 37, a reaction disk 35, the plate plunger 34, and the rubber damper 33. Since the valve plunger 17 can advance by compressing the rubber damper 33 when a brake pedal is stepped on from a servo balanced state, it can advance greatly with lighter pedaling power than in devices of the prior art in which it needs to compress the reaction disk when advancing.

Title: Picture recorder
Inventor: FUKUSHIMA HISASHI
IPC: G03G15/06
Filed: 1986-10-03
Abstract: PURPOSE:To prevent the sticking of toner or the like to the surface of an image carrier by controlling a developing bias voltage impressed to a developing device in accordance with the change of an electrostatic charging voltage to the image carrier. CONSTITUTION:When abnormality is generated in a transfer material 6, the impression voltage of a primary electrifier 2 is turned off and the electrified potential VD of a photosensitive drum 1 is gradually dropped from VD1. A potential sensor 12 detects the electrified potential VD at that time and outputs a detecting signal to a control circuit 13. The circuit 13 allows a developing bias voltage VB to be impressed to the developing device 5 to follow the attenuation of the electrified potential VD and controls the VB so that the VB is gradually dropped from VB1 and set up to a value lower than the electrified potential VD always by a prescribed voltage VBack. Since the voltage VBack can be always maintained even in the dropping of the electrified potential VD, Coulomb force (repulsive force) applied between the drum 1 and toner which are image carriers respectively having same polarity (minus) is always larger than that applied between the developing device 5 and the toner, so that the toner or the like is not stuck to the surface of the drum 1.
